Answer:

(0,-2)

Step-by-step explanation:

you can multiply the first equation by 6 and add it to the other equation to eliminate the x then you get -29y=58 then you divide both sides of the equation by -29 to get y=-2 so now you know x=0 and y =-2

Find the values of x and y.<br> help please work has to be shown ..
Likurg_2 [28]

Answer:

x = 7 and y = 17

Step-by-step explanation:

16x + 9x + 5 = 180 cuz they are supplementary

25x = 175

x = 7

We also know that 16x + 4y = 180

so 16(7) + 4y = 180, so 4y = 180 - 112, so 4y = 68. y = 17

hope this makes sense
